Secure Coding Practices in Game Development for Protecting User Data


Secure Coding Practices in Game Development for Protecting User Data

November 21, 2020

Game developers are increasingly facing the challenge of securing game-user data. Even though most game developers focus on creating a fun environment for their users to enjoy, they should not forget about security concerns. In this article, we will discuss how to secure coding practices in game development to protect user data and information from external threats.

Importance of Secure Coding in Game Development

The importance of secure coding in game development cannot be overstated. It is a top priority for all parties involved: the developers themselves, their users, the gaming industry as a whole and even members of the gaming community at large.

Security is essential for protecting user data from hackers and malicious actors who may want to access or steal it. If you have any doubt about this point, just look at recent events such as data breaches affecting major companies like Uber and Equifax (which was actually two separate incidents). These breaches resulted in millions of people having their personal information compromised and they were just the latest high-profile examples!

Data Security in Game Development

Data security is important for all businesses, but it’s especially crucial in game development. Data leaks can be damaging to your reputation and brand. They can also be embarrassing if they reveal sensitive information about your company or employees. And if you’re dealing with sensitive user data, the cost of a data breach could be enormous not just financially but also legally (think GDPR). This is why any reputable AAA game art studio turns to experts in the field to ensure their data is secure at the highest level.

Data security breaches have happened at some of the biggest companies in tech: Facebook lost control over user information when Cambridge Analytica used its platform to harvest data from millions of people; Google was fined $6 billion by the European Union after allegations that it manipulated search results; Uber concealed a cyberattack affecting 57 million users that occurred in 2016; Equifax announced a massive breach impacting 145 million Americans’ personal details including credit card numbers and social security numbers; Marriott revealed plans to launch an investigation into how its Starwood Hotels division had been hacked earlier this year resulting in 500 million guests being affected by the breach…the list goes on!

Authentication and Authorization

Authentication and authorization are two methods used in game development to ensure that only authorized users can access a system or resource. Authentication is the process of proving who you are, while authorization determines what actions you may perform based on your identity. Authentication methods include things like passwords and biometrics (like fingerprints), while authorization methods include access control lists (ACLs) and role-based access control (RBAC). Both authentication and authorization should be included when developing secure software systems.

A secure authentication method uses unique identifiers that cannot be replicated by an attacker to verify someone’s identity. For example: if an attacker steals your username/email address combination from one website then tries it on another site where they don’t have an account yet, they won’t be able to log into either site because those credentials aren’t valid anymore since they’ve already been used somewhere else before! This concept applies for any type of credential: if someone steals my password then tries using it elsewhere without my knowledge or consent then bad things happen because now I’m locked out from all my other accounts too!

Input Validation and Sanitization

Input validation is the process of validating user input before accepting it. Input sanitization is the process of sanitizing user input after accepting it. Both are important because they prevent malicious users from exploiting vulnerabilities in your app.

Input validation ensures that only appropriate data is entered into an application, while input sanitization cleans up potentially dangerous data such as HTML tags or SQL injection attacks before they reach your database layer or any other sensitive parts of your software stack.

Data Encryption

Encryption is a process of encoding data so that only authorized parties can read it. Encryption is required to protect user data, as well as communications between game servers and clients. Encryption also protects against hackers and cheaters who try to steal your game’s secrets by intercepting network traffic or modifying the code on their own computers.

Secure Communication Protocols


HTTPS is a secure protocol that ensures that all data sent between your server and client is encrypted, so it can’t be intercepted or tampered with by third parties. TLS is a standard for encrypting data sent over the internet, which includes HTTPS.


Encryption protects data from being read by unauthorized parties through the use of cryptographic algorithms and keys. It’s important to note that even if you’re using HTTPS/TLS, if you don’t encrypt your sensitive information before sending it across an open connection (like the internet), then anyone else who has access to that connection could potentially see what they’re sending even if they don’t know how exactly how the encryption works!

Secure Keys

When using encryption, there needs to be some sort of key generated so both sides know how much data they should keep secret versus making publically available (for example: credit card numbers). This key must remain secret at all times; otherwise hackers will be able to break into any system where this key exists without knowing anything else about how those systems work!

Patch Management and Updates

If you’re developing a game, one of the most important things is to keep it secure. In order for this to happen, you need to ensure that your users’ data is protected and not compromised. One effective method of achieving this is through patch management: applying updates from developers, such as, as soon as they become available. However, there are other ways in which you can protect your users’ information from being leaked or stolen by hackers and cybercriminals.

User Education and Awareness

You should also consider training users on security issues. Security awareness training is a great way to help people understand the importance of protecting their data, how to do so, and what types of threats might exist.

Training can be set up in many ways you could send out emails about new policies or changes in the system; you could create posters that go up around your office; you could even hold live presentations for groups of employees at once (or even better: individualized sessions).

You’ll want to measure how effective your training has been over time by asking questions like: Are there any gaps in knowledge? Do people feel more confident about protecting themselves against threats? Do they know where they should go if they see something suspicious happening on our platform?

There are many ways to secure your data while coding, but these are a few that help prevent accidental leaks of user data.

Authentication and Authorization

This is the process of ensuring that only authorized users can access restricted resources on your system. You can also use it to verify if an account has been compromised by an attacker or infected with malware. Authentication is done through passwords, biometrics and tokens while authorization uses access control lists (ACLs) which specify what actions a user can perform on different objects in the system.

Input Validation/Sanitization

Validating input means checking for format errors before processing it further into the program’s logic. Sanitizing means removing malicious characters from input fields so as not expose them directly into memory where hackers could exploit them later on during execution time when running code inside their own programs which could potentially allow them full control over any computer systems connected through network connections such as Wi-Fi signals etc.


The bottom line is that secure coding is important for game developers. It’s your responsibility as a developer to ensure that the user data you collect and store is safe from malicious attacks. This means using strong passwords, encrypting data when possible, limiting access to sensitive information on your servers through authentication/authorization protocols and more.
